Meanwhile, Ulster boss Les Kiss makes two changes to the starting team that defeated the French giants 38-0 last Friday, both of which come in the back row, as Kiss carefully manages his playing resources during a busy fixture schedule.

Sean Reidy is set to make his Champions Cup debut after being named at openside flanker, while Roger Wilson will start at number eight in place of Nick Williams.

Rory Best will again captain the side from hooker and will be flanked in the front row by Kyle McCall and Wiehahn Herbst. Alan O'Connor and Franco van der Merwe continue in the second row.

The backline is unchanged from last week; Ruan Pienaar and Paddy Jackson occupy the half-back positions, Stuart McCloskey and Luke Marshall start in midfield and Craig Gilroy, Andrew Trimble and Louis Ludik make up the back three.

Form: Ulster were the first team in Champions Cup history to keep Toulouse scoreless in a match when they beat them 38-0 in Round 3. Toulouse are still just 21 points shy of their 4000th in the Champions Cup. Toulouse have lost just twice in 10 home matches against Irish opponents in the Champions Cup. Toulouse have averaged the most (19) and Ulster the fewest (3.5) offloads per game this season in the Champions Cup.
